Answer:

x = 16

Step-by-step explanation:

Opposite sides are equal in a parallelogram

AD = BC

5x - 12 = 3x + 20

5x - 3x = 20 + 12

2x = 32

x = 32/2

x = 16

Answer:

x=3y

Step-by-step explanation:

divide both sides by 20

20x = 60y

x=3y

Answer:

x = 3y

Step-by-step explanation:

20x = 60y

Divide 20 into both sides.

20x/20 = 60y/20

1x = 6/2y

Answer:

0.4629 = 46.29% probability that the manager finds more than two such transactions

Step-by-step explanation:

For each transaction, there are only two possible outcomes. Either there is a procedural error, or there is not. The probability of a procedural error on a transaction is independent of any other transaction. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

In which \(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.

\(C_{n,x} = \frac{n!}{x!(n-x)!}\)

And p is the probability of X happening.

A manager randomly selected 25 large cash transactions at a bank that were made in January.

This means that \(n = 25\)

The chance for a procedural error is 10%

This means that \(p = 0.1\)

What is the probability that the manager finds more than two such transactions?

This is:

\(P(X \geq 2) = 1 - P(X < 2)\)

In which

\(P(X < 2) = P(X = 0) + P(X = 1) + P(X = 2)\)

\(P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}\)

\(P(X = 0) = C_{25,0}.(0.1)^{0}.(0.9)^{25} = 0.0718\)

\(P(X = 1) = C_{25,1}.(0.1)^{1}.(0.9)^{24} = 0.1994\)

\(P(X = 2) = C_{25,2}.(0.1)^{2}.(0.9)^{23} = 0.2659\)

\(P(X < 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0718 + 0.1994 + 0.2659 = 0.5371\)

\(P(X \geq 2) = 1 - P(X < 2) = 1 - 0.5371 = 0.4629\)

0.4629 = 46.29% probability that the manager finds more than two such transactions

Using the binomial probability relation, the probability that more than 2 such transactions is made is 0.463

Given the Parameters :

Using the relation :

Substituting the values into the relation :

P(X > 2) = P(X = 3) + P(X = 4) +... + P(X = 25)

Using a binomial probability calculator :

P(X > 2) = P(X = 3) + P(X = 4) +... + P(X = 25)

P(X > 2) = 0.226 + 0.138 +... +..

P(X > 130) = 0.463

The probability that more than 2 such transactions is made is 0.463

The best measure of VARIABILITY for the number of people riding each boat at the club on a Saturday morning as recorded by the boat club manager is D. mean absolute deviation.

The mean absolute deviation (MAD) is the mean or average distance between each data value and the mean of the data set.

The mean absolute deviation (MAD) quantifies the data spread.

The MAD is computed by taking each number in the data set, subtracting the mean, and taking the absolute value, which is summed.

Then this sum is divided by the total number of values in the data set.

The unknown measures are from right angle triangle is

KM = 10.68

∠m = 35 and ∠k = 55

Given that

KL =6.2

LM =8.7

KM = x

The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

The triangle that is presented is a right angle triangle.

\(KM^{2}\) = \(LM^{2}\) + \(KL^{2}\)

KM = \(\sqrt{(8.7)^{2} + (6.2)^{2} }\)

KM = \(\sqrt{114.13}\)

KM = 10.68

Now figure out the angles.

∠m = sinm

Answer:

f(100) = 160.

Step-by-step explanation:

Linear function:

The equation of a linear function has the following format:

\(y = mx + b\)

In which m is the slope(how much f(x) changes when x changes by 1) and b is the y-intercept(value of f(x) when x = 0).

Finding the slope:

Suppose we have two points. The slope is the change in the output divided by the change in the input.

In this question, we have points (45,50) and (60,80).

Change in the output: 80 - 50 = 30

Change in the slope: 60 - 45 = 15

Slope: 30/15 = 2

So

\(y = 2x + b\)

Point (45,50)

This means that when \(x = 45, y = 50\). We use this to find the value of b.

\(y = 2x + b\)

\(50 = 2(45) + b\)

\(b = -40\)

So

\(y = 2x - 40\)

With y = f(x)

What is the value of f(100)?

This is y when x = 100. So

\(f(100) = 2(100) - 40 = 200 - 40 = 160\)

f(100) = 160.

To subtract 47.96 from 320.041, you can align the decimal points and then subtract each digit from right to left.

First, write the numbers with the decimal points aligned:

320.041

- 47.960

Next, subtract the digits in the ones place, which is 1 minus 0, resulting in 1. Then, subtract the digits in the tenths place, which is 4 minus 6. Since 4 is less than 6, you need to borrow 1 from the digit to the left, making the 2 into a 1 and adding 10 to the 4, giving you 14. So, 14 minus 6 equals 8.

Continue subtracting each digit in the same way:

   320.041

-   47.960

= 272.081

Therefore, 320.041 minus 47.96 is equal to 272.081.

Answer:

Step-by-step explanation:

J:  y = 29 cm + (1 cm/mo)x

Z:  y = 12 cm + (2 cm/mo)x

29 cm + (1 cm/mo)x =  12 cm + (2 cm/mo)x

Solve for x to find how many months it will take for them to have the same length of hair:

29 cm - 12 cm = (2 cm/mo)x - (1 cm/mo)x

17 cm = (1 cm/mo)x

x = (17 cm) / (1 cm/mo) = 17 months

Plug this value for x (17 months) into the equations to find how long their hair will be:

J:  y = 29 cm + (1 cm/mo)(17 mo) = 46 cm

Z:  y = 12 cm + (2 cm/mo)(17 mo) = 46 cm

This shows that it will take 17 months for each girl's hair to be 46 cm long.
